Biopolymers are one of environment-friendly materials that can be completely degraded by microbes, not like other chemical products. It is more effective to saturate the pore of soils by biopolymer solutions than by water, and therefore biopolymers are used for soil remediation and petroleum production. Two types of biopolymers, alginic acid sodium salt (SA) and polyethylene oxide (PEO), are employed in this study to experimentally investigate the basic properties - contact angle, surface tension, viscous force - and flow characteristics of biopolymer solutions using microfludic device. It was found that the contact angles of biopolymer solutions on a silicon dioxide plate were lager than that of water. The magnitudes of surface tensions of biopolymer solutions did not show a clear trend. The viscous force of biopolymer solutions were larger than that of water, and it increased with increasing concentration of solutions. The tests with a microfluidic device showed that the pore is better saturated by the biopolymer solutions with more concentration and more injection velocity. The results of this study provides basic properties of biopolymer solutions for flow analysis, and can be referenced for effective soil remediation and petroleum production usingn biopolymer solutions.
